'NEUMANR HINGE FOR BAG FRAMES.

Application filed December The present invention relates, generally, to improvements in hinges; and, the invention has reference, more particularly, to that class of hinges which are used for opera- .tively connecting the two frame-sections of a bag-frame, with a view of providing a novel and simply constructed three-part hinge, which is readily applied to the bagframe, and is of such arrangement and construction of parts, so that the two frame members or sections of thebag-frame ale retained in their opened relation, but still permits of the closing of the frame-sections.

The present invention, therefore, has for its rincipal object the production of a novel and simply constructed bag-frame hinge in which the parts have been reduced to a minimum, which is readily secured in its operative position to the framesections, and operates to hold the frame-sections in their opened relation, but at the same time permits the opened bag-frame sections to be easily and quickly closed without any further manipulation onthe part of the operator.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

lVith the various objects of the present invention in view, the said invention consists, primarily, in the novel bag-frame and hinge-connection therefor, and hereinafter set forth; and, the invention consists, furthermore, in the details of the construction of the parts of the said bag-frame and its hingerconnection more fully described in the following specification, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which 2- Figure 1 is an elevation of one of the hinge-connections-of a bag-frame, looking toward the inner face-portions of the framesections, the latter and the parts of the hinge connected therewith being represented in their closed relation; and Figure 2 is a similar view of the parts shown in said Figure 1, the frame-sections and members of the hinge being represented in their opened relation.

Figure 3 is a top or plan view of the parts represented in said Figure 2; and Figure 4 is a longitudinal, vertical section of he sal n 8,1925. ser al No, 73,985.

of a cam-shaped stay-member of the hinge. 9 i Similar characters of reference are employed in the above described views, to indlcate corresponding parts. 7 H

Referring now to the several figures of the drawings, the reference-characters l and 2 indicate the leg-portions forming the ends of the usual framessections of a bag-frame, to be operatively connected, as in the present case, by means of hinges 3 made according to and embodying the princip'lesof the present invention, it being understood that with each bag-frame two of such hinges are used.

As shownin the several figures of. the drawi'ngs,each hinge consists of two hingeplates 4 and 5, the plate 4 being formed at one of its end-portions with angularly bent extensions 6 and, 7, having a-space 8 be tween them, and the extension 7 which is of greater length than the extension 6 being provided at itsfree end witha pintle-receiving eye, as 9. The said hinge-plate 4 is also provided with perforations 10 for the reception of rivets 11, or the like. for securing the same in its operative position, in the manner shown, to the leg-portion 1. In a similar manner, the hinge-plate 5 is formed at one of its end-portions with angularly bent extensions '12 and 13, having a space 14 be tween them, and the extension 13 which is of greater length than the extension 12 be- 7 ing provided at its free end with a pintlereceiving eye, as 15. The said hinge-plate 5 is also provided with perforations 16 for the reception of rivets 17, or the like, for securing the same inits operative position, in the manner shown, to the leg-portion2. The reference character 18 indicates a suitably shaped stay-member from the main bodyportion of which-extend asset of fingers or horns 119 and 20, having a space 21 between themof awidth substantially equaltothe thickness/of the hinge-plate 5,,The bodyportion of said stay-member is also provided with a. pintle-receiving perforation 22, and with a marginal projection 23, forming with the fingeror horn 20 a marginal depression, as 24. In their assembled relation, the space 21 between the fi ge r hare 19 and 2 is brought into alincment with the space 14 between the extensions 12 and 13 of the hinge plate 5, the said fingers or horns 19 and 20 being forced into frictional engagement, respectively, with the upper and lower faceportions of the angular portion of the said hinge-plate 5, as indicated in Figure 4 of the drawings, the pintle-receiving eye'15 being brought into lateral alinement with the perforation 22. Next, the space 8 between the extensions 6 and 7 of the hinge-plate 4 is arranged over the edge-portion 25 of the bodyportion of the stay-member, until the pintlereceiving eye 9 is brought into lateral aline ment with the perforation 22, the pintlereceiving eyes 15 and 9 thus being located on opposite sides of the bodyportion of the stay-member, as will be evident. The various parts are then pivotally connected by means of a pintle 26. The completed hinge. thus provided, is next secured to the legportion 2 by means of the rivets 17, and to the leg-portion 1 by means of the rivets 11. a flat spring-plate 27, suitably perforated, being first placed between the hinge-plate 4: and the leg-portion 1, and simultaneously secured. in position with said hinge-plate 4 by means of the said rivets 1.1. As shown, the said springplate 27 has a portion extending beyond the end of the leg-portion 1, said projecting portion being suitably bent or curved, as at 28 and 29, adapted to be brought into retaining or holding eugagen'ient, respectively, 'ith the marginal surface-portions of the projection 23 and the depression 24-. when the parts are in their opened-out positions represented in Figures 2, 3 and at of the drawings.

The slidable arrangement of the bent or curved portions 28 and 29 of the spring-plate 27 with said projection 23 and depression 24 will be fully understood from an inspection of said Figures 2 and a of the drawings, and it will be evident that when the bag :i'rame-sections are opened they will be fully and positively retained inv their opened relations against accidental closing.

It will also be evident from the arrange ment and construction of the parts that after the frame-sections have been opened they can be readily closed without the least danger of ('lestroying the opcrativenoss and usefulness of the hinged connections.

From the foregoing description of the present invention, it will be clearly evident that a neat and simply constructed bag-frame hinge has been produced,the hinged connections of which form are readily secured to the respective frame-sections, so that a much stronger, and at the same time a cheaper construction is the result; and, furthermore, a better and much more neatly finished hinged connection is produced.

I am aware that some changes may he made in the arrangements and combinations of the various parts without departing from the scope of my present invention as setforth in the foregoing description, and as defined in the clauses of the claims, which arc appended to the said specification. Hence, I do not limit my present invention to the exact arrangements and combinations of the various parts as described in the foregoing specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.

1 claim 1. A hinge for the frame-sections of a bagt'rame, comprising a pair of hinge'plates, fingers extending from an end-portion of each hinge-plate, one of the fingers of each hinge-plate being of greater length than its adjacent linger, said longer fingers being provided with pintle-receiving eyes, and each pair of fingers having a space between them, a stay-member having portions arranged in said spaces, said stay-n'ien'iber be ing pr wided with a perforation, and a pin tle arranged in the eyes of the fingers of the respective hinge-plates and in the perforation of said stay-member.

2. A hinge for the frame-sections of a bagframe, comprising a pair of hinge-plates, lingers extending from an end-portion of each hinge-plate, one of the fingers of each hingeplate being of greater length than its adjacent finger, said longer fingers being provided with pintle-receiving eyes, and each pair of fingers having a space between them, a stay-member having portions arranged in said spaces, said stayanember being provided with apcrforation, and a pintlc arranged in the eyes of the fingers of the respective hinge-plates and in the perforation of said stay-member, said stay-men'iber having a marginal projection. and a marginal (lBPI'GQ- sion, associated with a spring-plate having portions adapted to be moved into and out of sliding engagement with said projection and depression.

In testimony, that 1 claim the invrnt'on set forth above .I have hereunto set my hand this ith day of December, 1925.
